The Lime scooter company partnered with Georgia Tech's HIVE Makerspace and donated 200 scooters worth of parts to see what kind of great projects and inventions we could come up with. I took it upon myself to make sure the resources and information were available to everyone who wanted to start their own project by tearing apart and documenting everything inside the scooters by labeling, adding notes, measurements, and tips so everyone else can easily figure out what they need to do to get their project off the ground. Examples of projects that ended up using these scooter parts and my documentation range from a racing couch, to a new open source Brushless DC motor controller that ended up being used by a university e-racing team in Brunei. However, the project I was the most involved with was working on this electric minibike! It has a top speed of about 12 miles an hour and has some really cool features:

  1. Electric throttling

  2. Battery estimation

  3. Speedometer

  4. Indicator lights such as brakes, turn signals, and hazards

  5. LED Headlight

  6. It looks awesome

​

The next project I'm going to be making with the last few Lime parts I managed to save is my own electric go-kart! It's going to be a little more difficult since it's going to have to coordinate 2 separate powered wheels instead of just 1 which could get a little interesting. I'm excited to see what I can do and what features I can implement with this project.

​

This is an ongoing venture in conjunction with the HIVE as well as the Lime scooter company.
